This paper considers the sealed bid and ascending auction, which both identifies the minimum Walrasian equilibrium prices and where truthful preference revelation constitutes an equilibrium. Even though these auction formats share many theortical properties, there are behavioral aspects that are...

This paper revisits the fair and optimal allocation mechanism (Sun and Yang, Economics Letters 81:73-79, 2003) and demonstrates that it is coalitionally strategy-proof. The proof is valid for general preferences, it is simple and it is short.

This paper analyzes the problem of selecting a set of items whose prices are to be updated in the next iteration in so called simple ascending auctions with unit-demand bidders. A family of sets called "sets in excess demand" is introduced, and the main results demonstrate that a simple...

This paper considers the sealed bid and ascending auction, which both identifies the minimum Walrasian equilibrium prices and where truthful preference revelation constitutes an equilibrium. Even though these auction formats share many theoretical properties, there are behavioral aspects that...

This paper investigates empirically a number of hypotheses that are related to efficiency and price uniformity in online competing auctions for train tickets. The data set is ideal for analyzing competing auctions since each ticket is sold in a separate auction and all auctions with identical...

This note analyzes constrained Pareto efficient nonlinear income tax schedules that are monotonic chains to the left. The main result demonstrates that if all individuals have a positive consumption at the tax schedule that maximizes the utility of the worst-off individual, then the constrained...

This paper considers two multi-item auction formats (ascending and sealed bid) which both identify the minimum Walrasian equilibrium prices and where truthful preference revelation constitutes an equilibrium. Even though these auction formats share many theoretical properties, there are...

A group of heterogenous agents may form partnerships in pairs. All single agents as well as all partnerships generate values. If two agents choose to cooperate, they need to specify how to split their joint value among one another. In equilibrium, which may or may not exist, no agents have...

This paper characterizes nonlinear outlay schedules that are based on a cooperative surplus sharing game with transferable utility. First, the pricing game is shown to be convex and, as a consequence, to have a non-empty core. This is followed by a description of the necessary and sufficient...
